Reviewing classics can be humbling. Some books have passed through so many generations and have been analyzed so thoroughly that they've reached mythic proportions. Only the arrogant or ignorant would criticize them. On War is just such a book.

First the disclaimer. I have an amateur interest in military history but do not have the depth to fully appreciate mid-19th century military theory. Regardless, I know enough to appreciate Clausewitz's rejection of formulated tactics and movement.

"War is simply the continuation of politics by other means."

Far too many people quote Clausewitz without read him, but after reading this edition of On War, there is no excuse not to read Clausewitz, and perhaps understand him.

I will speak first to the translation: This is how it should be done. Howard, Paret, and Brodie produce an accurate and highly readable text, with invaluable supplementary essays on the historical impact of Clausewitz and his key points. Accept no other translations.

Almost 200 years later, this masterpiece is still misunderstood and ignored.

Clausewitz argues that the purpose of war is to disarm your opponent and thereby force him to give you want you want. Based on this premise, he concludes that wars are essentially unwinnable on the battlefield: it is virtually impossible to completely disarm your opponent through might alone. Instead, your opponent at some point has to decide to give you want you want--and getting your opponent to come to that decision m
No one can actually enjoy reading Clausewitz - it simply must be done.
One of the most difficult books I've ever read (so far). Took me a month just to read it, and sadly not 100% able to understand the whole thing. This one needs a re-read someday. Some parts are just so indigestible and make me want to pull my hair due to frustration.

Having said that, why I gave this book four stars? Well, first it is a challenging read and I like challenges. Secondly, the contents are unbelievable. Yes, some explanations may be outdated, but the gist is still relevant. If one co

It's hard to write a review of such a disjointed work. The important points he hits on are indeed extremely important, but wading through 750 pages of repetitive and wordy abstract run on sentences gets old pretty quickly. Two most important points:

1) Why don't nations fight wars of annihilation (remember, this is the early 19th Century, he doesn't know about the World Wars)? Well, why don't school children carry on their fights to the death? Answer: doing so isn't anywhere near worth the cost.

This is the classic work of military strategy, written by a Prussian general in the nineteenth century, which has been often discussed but little understood. It is often held up as the ultimate example of “Prussianism,” of stifling military correctness, or as the champion of “absolute war” and the use of brutality and abandonment of rules in order to annihilate the enemy. It is blamed for the outbreak of both World Wars and for the horrors which those and subsequent conflicts loosed on the world ...more

This book stands as an important and modern classic about the nature of war. Clausewitz applies rigorous analysis to almost all the factors that influence war, not least of which are social and political aspects. Indeed, for him, war is part of man's social existence, and politics the womb in which war develops. This is encapsulated in his famous comment: "War is merely the continuation of policy by other means."

There are a number of intriguing and developed insights within this book: how defens
Five stars for the translation which is simply the best on the market, and includes a superb commentary by Bernard Brodie. This is my fourth time reading this in the context of a class (Naval War College) and it is not any easier to navigate or understand, however, it is never a waste of time.

Clausewitz himself gives the best summary of this work on p. 89: "First, therefore, it is clear that war should never be thought of as something autonomous, but always as an instrument of policy; otherwise

Without doubt the best book about war ever written!
Even after all this time (how long has it been since it was written? centuries!) it is not dated. Really, it is not dated.

Carl Von Clausewitz is the first theorist of war (and he remains the best). Moreover, he is the first to write and understand war fully. There are other great books on this subject such as those written by Machiavelli and Sun Tzu but this is a theory, a great theory of war. Just like Sun Tzu and Machiavelli, the author creat

With the understanding of certain tactical level chapters being outdated, it is still a phenomenal read for strategic and operational theorizing, but must be consumed slowly, deliberately, and with much contemplation. Superficial hypocracy and seeming contradictions are eliminated with careful evaluation, intellectually Clausewitz reduces issues to their theoretical, most simplistic forms, and then walks them back with elaboration of the real world complications that prevent and contrive a perfe ...more

As a sometime student of History and War Studies I read this book a long long time ago in a galaxy far far away...

I have the abridged Wordsworth Classics edition, abridged because the original consists of eight books in three volumes, and of course was written in German, so it's not a light read.

On War is certainly one of the great books of military history. It is probably also one of the most dangerous, because his theories can, and have been, taken out of context and misused as justification f

Ranked one of the great contributions in the literature of war, Clausewitz's book, "On War", presents a wide-ranging and very intellectual discussion of the subject of war. There is room for debate about precisely what the book is about.  But Clausewitz is emphatic about what it is not: it is not a book on doctrine; it does not presume to give definitive tactical lessons; it does not pretend to give a formula on strategy-making. These are not Clausewitz's purpose. Rather it is theory that he say ...more

This review is on the abridged Reclam edition of the text.
It is hard to classify what type of book this is. What it is certainly not, is a textbook on military tactics. In its different parts, it contains a meta-analysis of war, aimed at dispelling many of the theoretical beliefs on war at the time, a psychological and sociological analysis of the countries in war, the military and its leaders, and it also contains a good deal of advice on large-scale military strategy.

"On War" is one of those books that was at the same time amazingly influential and almost never actually read. While Clausewitz is quoted and discussed by military men repeatedly, it fascinates me how many military officers serve long and distinguished careers without ever having read this book. In many ways this is understandable. Clausewitz is very philosophical and abstract, to the point that many of his ideas are simply not applicable to everyday military planning. One must also remember tha ...more

This is one of those classics that I've read sections of, read discussions of, read debates about, but hadn't actually read from cover to cover. Until this year.

First, a couple of notes about this edition. Goodreads has (at this writing) the wrong total page count for the book. My copy, at least, has 936 pages. Also, a fascinating element of having the Graham translation (with his footnotes) as edited by Maude (with his footnotes) is that you get glimpses of how this was taken in the late 1800s

Okay, so this is a long book--over 600 pages--and some of it is a slog--like a battle that has gone on too long, with the reader's army expending a lot of energy and time to finish. But, it can be useful. The book I mean. Even as we don't fight wars in our everyday lives, we can use this book to solve problems and conflicts. Maybe. I haven't put its advice and strategies into action yet. But, here's hoping. Among much advice, Clausewitz says war is politics by other means. He urges it to be deci ...more

On War is often considered tedious, long, and difficult to read. Those who promote this argument certainly have some valid points, and their concerns were echoed by Clausewitz's contemporaries, which led to Antoine Henri Jomini achieving far more prominence in military circles before 1914. However, despite Jomini's continued influence in the concept of "scientific principles of war", Clausewitz's On War has proved instrumental in shaping the foundations of today's military theory and thought.

There are scores of books throughout history that have stood the test of time and remain relevant even today. To Clausewitz's credit, "On War" is one of them. Unfortunately, while Clausewitz's observations may be timeless, his writing style and voice are horribly out of date. His treatise is obtuse, repetitive, and rife with long-winded, complicated sentences.

It is true that he was a soldier and not a writer, and that his holistic view of war has shaped the manner in which armed conflict is cond

This is the other book, after "The Art of War", in the popular mind when it comes to military theory. I believe it is far superior as well. It only doesn't receive 5 stars from me because it was never finished and this results in two big setbacks: 1) The book on "The Attack" is mostly notes, with even barer concepts (Clausewitz is excellent in simplifying concepts, but in this book the lack of treatment works against that simplicity) and 2) There are important final chapters in the last book "Pl ...more

Recommends it for: anyone young and foolish enough to become an army officer
Dubbed "Sun Tzu from the West", I rushed to buy this book after it was mentioned in my fave movie Crimson Tide. Turned out to be as indigestible as unthawed frozen food. So much with my youth's dream of becoming a general and invade Malaysia....

One point from the book still rings in my head though: "you only achieve complete victory if you have broken the enemy's WILL to fight". As long as there is will to resist and fight, the enemy will be a pain in the ass, no matter how poorly equipped they
I listened to Volume 1.
Carl von Clausewitz like Marcel Proust takes delight in unnecessarily complicated sentences. His style of writing isn't very suitable to the audiobook format.
In the beginning he spends some time defining fundamentals and debunking bullshitters.
His writing is most interesting when he uses examples to illustrate his ideas.
Ultimately, I was bored too often and his remarks frequently couldn't capture my attention, 2,5 stars.
Who am I to critique Clausewitz? Honestly, everything he says could be written in about 40% of the space he takes, but his kernels of truth remain so and ever shall. Worth everyone's time (especially in this abridged version, which cuts out much of the period-specific tactica on terrain and investing fortresses and the like).

So, after taking a week to really chew up and digest Uncle Carl, I see how and why a lot of people get his propositions wrong! They get his theory wrong, and then mis-apply it to modern day situations without fully understanding his context. I know for a fact this week has help to make me a better military thinker for gaining a better understanding and appreciation of Clausewitz!

Clausewitz has served in the Rhine campaign (1793–1794), when the Prussian army invaded France during the French revolution and in the Napoleonic Wars from 1806 to 1815.
